使用VBScript从ZIP文件中提取文件

从ZIP文件中提取文件时,我使用以下内容.

Sub Unzip(strFile)
' This routine unzips a file. NOTE: The files are extracted to a folder '
' in the same location using the name of the file minus the extension.  '
' EX. C:\Test.zip will be extracted to C:\Test '
'strFile (String) = Full path and filename of the file to be unzipped. '
Dim arrFile
    arrFile = Split(strFile, ".")
    Set fso = CreateObject("Scripting.FileSystemObject")
    fso.CreateFolder(arrFile(0) & "\ ")
    pathToZipFile= arrFile(0) & ".zip"
    extractTo= arrFile(0) & "\ "
    set objShell = CreateObject("Shell.Application")
    set filesInzip=objShell.NameSpace(pathToZipFile).items
    objShell.NameSpace(extractTo).CopyHere(filesInzip)
    fso.DeleteFile pathToZipFile, True
    Set fso = Nothing
    Set objShell = Nothing
End Sub 'Unzip

这是有效的,但现在我得到一个"文件存在"错误.

这是什么原因？还有其他选择吗？

以上所有解决方案都是准确的,但它们并不确定.

如果您尝试将压缩文件解压缩到临时文件夹中,将立即为您尝试提取的ZIP文件中包含的每个文件创建一个显示"YOURFILE.zip的临时文件夹"的文件夹(在C:\Documents和中Settings\USERNAME\Local Settings\Temp).

没错,如果你有50个文件,它会在你的临时目录中创建50个文件夹.

但是如果你有200个文件,它将停在99并崩溃说明 - 文件存在.

..

显然,这在Windows 7上不会出现我上面提到的贡献.但无论如何,我们仍然可以进行检查.好的,这就是你解决它的方法:

    '========================
    'Sub: UnzipFiles
    'Language: vbscript
    'Usage: UnzipFiles("C:\dir", "extract.zip")
    'Definition: UnzipFiles([Directory where zip is located & where files will be extracted], [zip file name])
    '========================
    Sub UnzipFiles(folder, file)
        Dim sa, filesInzip, zfile, fso, i : i = 1
        Set sa = CreateObject("Shell.Application")
            Set filesInzip=sa.NameSpace(folder&file).items
        For Each zfile In filesInzip
            If Not fso.FileExists(folder & zfile) Then
                sa.NameSpace(folder).CopyHere(zfile), &H100 
                i = i + 1
            End If
            If i = 99 Then
            zCleanup(file, i)
            i = 1
            End If
        Next
        If i > 1 Then 
            zCleanup(file, i)
        End If
        fso.DeleteFile(folder&file)
    End Sub

    '========================
    'Sub: zCleanup
    'Language: vbscript
    'Usage: zCleanup("filename.zip", 4)
    'Definition: zCleanup([Filename of Zip previously extracted], [Number of files within zip container])
    '========================
    Sub zCleanUp(file, count)   
        'Clean up
        Dim i, fso
        Set fso = CreateObject("Scripting.FileSystemObject")
        For i = 1 To count
           If fso.FolderExists(fso.GetSpecialFolder(2) & "\Temporary Directory " & i & " for " & file) = True Then
           text = fso.DeleteFolder(fso.GetSpecialFolder(2) & "\Temporary Directory " & i & " for " & file, True)
           Else
              Exit For
           End If
        Next
    End Sub

就是这样,将这两个功能复制并粘贴到您的VBScript托管程序中,在Windows XP和Windows 7上应该不错.

谢谢!
